Abstract
Provided is a microstrip antenna applied for a digital interphone. The microstrip antenna comprises an upper antenna and a lower antenna; the upper antenna comprises an upper antenna substrate fixing seat, an upper medium substrate, a spring strip which is used for connecting the lower antenna and arranged on the upper medium substrate, and a first radiation metal part electrically connected with the spring strip; the lower antenna comprises a lower substrate fixing seat, a lower medium substrate and a second radiation metal part arranged on the lower medium substrate; and a spring strip connection feedback point which is used for being electrically connected with the spring strip so as to be connected with the upper and the lower antennas is formed on the second radiation metal part. According to the utility model, via the combination of the upper antenna and the lower antenna, the size of the microstrip antenna can be effectively reduced, the microstrip antenna is more beautiful, and is arranged in the small interphone, so good signal receiving and sending performance of the microstrip antenna can be ensured, and the microstrip antenna is more firm, longer in service lifetime and more stable in performance.
Description
Technical field
The utility model relates to a kind of antenna, particularly a kind of microstrip antenna that is applied to digital handset.
Background technology
Because electronic installation now moves towards microminiaturized design, cause casing of electronic apparatus inner space narrow and small, can allow that the space that antenna puts is also more and more narrower and small.And at present, the antenna size being applied in prior art in intercom is larger, outward appearance is more not attractive in appearance, and is installed in the device of narrow space, can affect the signal transmission effect of antenna.Therefore, develop a kind of antenna, antenna size can be dwindled be arranged in small-sized interphone device, and guarantee that signal receives, sends functional, needs the problem of solution just badly.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, and a kind of compact size is provided, and has more aesthetic property, there is good reception, send performance, and more firm, long service life, the microstrip antenna that is applied to digital handset of stable performance.
The utility model adopts following technical scheme:
A kind of microstrip antenna that is applied to digital handset, include top antenna and bottom antenna, described top antenna includes a top antenna substrate holder, a top medium substrate and is arranged at one on the medium substrate of top for connecting shell fragment and the one first radiation metal portion of bottom antenna, described first radiation metal portion one end is electrically connected to shell fragment, and the other end forms open circuit; Described bottom antenna includes a bottom antenna substrate holder, a bottom medium substrate and is arranged at the second radiation metal portion on the medium substrate of bottom, described the second radiation metal portion is formed with one and to connect the shell fragment of upper and lower part antenna, connects feedback point, the mobile communication device terminals of an earth terminal and for being connected with the circuit board of mobile communication device for being electrically connected to described shell fragment, and the earth terminal of described upper and lower part medium substrate and the second radiation metal portion is all connected in the circuit board of mobile communication device.
Preferably, described first, second radiation metal portion is made by metal material, by printing or etching technique, is formed at respectively on the medium substrate of described upper and lower part.
Preferably, described first, second radiation metal portion is made by metal material, by printing or etching technique, is made.
Preferably, the specific distance of described top antenna is less than 1mm.
Preferably, the specific distance of described bottom antenna is less than 1.5mm.
Preferably, the circuit board of described mobile communication device also disposes match circuit, and with standby adjustment antenna impedance, match circuit comprises at least one shunt inductance and at least one series capacitance.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: the mode that adopts top antenna to combine with bottom antenna, can effectively dwindle antenna size, improve the aesthetic property of antenna, and be arranged in small-sized interphone device, can guarantee that antenna has good signal and receives, sends performance, simultaneously, because top antenna is connected by shell fragment mode with bottom antenna, can effectively avoid upper and lower part antenna loose contact, make antenna more firm, improved useful life, and performance is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be the utility model embodiment antenna return to loss figure.
In figure: 1. top antenna, 10. top antenna substrate holder, 11. top medium substrates, 12. shell fragments, 13. first radiation metal portions, 2. bottom antenna, 20. bottom antenna substrate holders, 21. bottom medium substrates, 22. second radiation metal portions, 23. shell fragments connect feedback point, 24. earth terminals, 25. mobile communication device terminals.
Embodiment
Below by embodiment, the utility model will be further described.
With reference to Fig. 1, a kind of microstrip antenna that is applied to digital handset of the present utility model, include top antenna 1 and bottom antenna 2, described top antenna 1 includes a top antenna substrate holder 10, a top medium substrate 11 and is arranged at one on top medium substrate 11 for connecting shell fragment 12 and the one first radiation metal portion 13 of bottom antenna 2, described first radiation metal portion 13 one end are electrically connected to shell fragment 12, and the other end forms open circuit; Described bottom antenna 2 includes a bottom antenna substrate holder 20, a bottom medium substrate 21 and is arranged at the second radiation metal portion 22 on bottom medium substrate 21, and described the second radiation metal portion 22 is formed with one and to connect the shell fragment of upper and lower part antenna, connects the mobile communication device terminals 25 of feedback point 23, one earth terminal 24 and for being connected with the circuit board of mobile communication device for being electrically connected to described shell fragment 12.
With reference to Fig. 1, the earth terminal 24 of described upper and lower part medium substrate and the second radiation metal portion 22 is all connected in the circuit board of mobile communication device.The circuit board of described mobile communication device also disposes match circuit, and with standby adjustment antenna impedance, match circuit comprises at least one shunt inductance and at least one series capacitance.
